.SH "NOM"
sulogin \- Single\-user login
.SH "SYNTAX"
.PP
\fBsulogin\fR
[\fItty\-device\fR]
.SH "DESCRIPTION"
.PP
The
\fBsulogin\fR
command is invoked by
\fBinit\fR
prior to allowing the user access to the system when in single user mode\&. This feature may only be available on certain systems where
\fBinit\fR
has been modified accordingly, or where the
/etc/inittab
has an entry for a single user login\&.
.PP
The user is prompted
.PP
Type control\-d to proceed with normal startup, (or give root password for system maintenance):
.PP
Input and output will be performed with the standard file descriptors unless the optional device name argument is provided\&.
.PP
If the user enters the correct root password, a login session is initiated\&. When
\fIEOF\fR
is pressed instead, the system enters multi\-user mode\&.
.PP
After the user exits the single\-user shell, or presses
\fIEOF\fR, the system begins the initialization process required to enter multi\-user mode\&.
.SH "AVERTISSEMENTS"
.PP
This command can only be used if
\fBinit\fR
has been modified to call
\fBsulogin\fR
instead of
/bin/sh, or if the user has set the
\fIinittab\fR
to support a single user login\&. For example, the line:
.PP
co:s:respawn:/etc/sulogin /dev/console
.PP
should execute the sulogin command in single user mode\&.
.PP
As complete an environment as possible is created\&. However, various devices may be unmounted or uninitialized and many of the user commands may be unavailable or nonfunctional as a result\&.
.SH "CONFIGURATION"
.PP
